I think that in order not to face such situations, all users should first check the terms and conditions of the casino they are going to invest money in and also check the tutorial videos if there are any tutorials on the things they don't understand.
The reading culture has to also be encouraged too by casinos because they have to make their terms and conditions very readable that new gamblers on their platform are not forced to skip them because of how unreadable they look.
Also if it is possible, I advise that these tutorial videos be made to pop up more than once so that even if a new gambler skips the videos the first time they are on the platform to gamble it will pop up again the second time or a few times more for them to see.
